air speed in pipe, pump gas vs e85

Got any approximate numbers?

550m/s seems to be whats used for gas nowadays.

I don't have a clue what you are talking about. 550m/s ?

Ment speed of sound.

I'm talking about calculating approximate pipe dimensions, e85 burns cooler = slower waves, but I'm not shure by what factor.
